Beginning April 27, licensed pesticide contractors working for Washington State Parks will be spraying noxious weeds along the egress road and parking areas of the Nine Mile Recreation Area, under the power lines near Inland Road, along sections of the Knothead Valley Trail and along W. Rutter Parkway, near the Indian Painted Rock Trailhead. This work will take several weeks to complete. Controlling noxious weeds helps to protect native plants and animal habitat. This work will address the following species of noxious weeds: Bugloss, Blueweed, Dalmation Toadlfax, and Rush Skeletonweed. Because of their aggressive growth these species can be destructive, competitive, and difficult to control. For questions about the work please contact the Riverside State Park office at 509-465-5064.
